Walter 3/8-16 NC HSS Bottoming Tap for Blind Holes

Reliable Threading for Fabrication and Repair

When you are in the middle of a fabrication project or repairing critical shop machinery, a broken or dull tap is the last thing you need. The Walter 3/8"-16 NC Bottoming Tap (03B063) is built for the professional welder and fabricator who demands tools that work as hard as they do. Made from heavy-duty High Speed Steel (HSS), this tap cuts through metal smoothly and reliably, ensuring you get the job done right the first time. It is designed to handle the rigors of daily shop use, cutting clean threads in everything from structural mild steel to gummy aluminum and tough stainless steel.

Maximize Thread Depth

Have you ever drilled a hole that doesn't go all the way through a plate, only to find your bolt won't tighten down because the threads stop too short? That is where this bottoming tap shines. With a chamfer of just 1.5 to 2 threads, it cuts full-depth threads virtually to the bottom of a blind hole. This allows you to use shorter bolts or maximize the holding power in thinner materials where you cannot drill through. It is the perfect finishing tool to follow up a taper or plug tap, ensuring your fasteners seat properly and securely.

Built to Last

Walter tools are synonymous with industrial quality. This tap features precision-ground threads that reduce friction and torque requirements, making hand-tapping easier and reducing the risk of breakage. The HSS material resists heat buildup, which is the enemy of sharp cutting edges. This means you can tap more holes per tool compared to cheaper carbon steel alternatives. Whether you are building custom frames, repairing engine components, or fabricating jigs, having a high-quality bottoming tap in your toolbox is essential for professional results.
